Bellows and method for manufacturing same |
摘要 |
A conductive coating layer 2a, 2b is formed on at least one of an inner peripheral side and an outer peripheral side of a base body 2 of bellows 1 by diffusion-bonding. Regarding the diffusion-bonding, the flat conductive coating layer 2a, 2b is layered on at least one end surface side of the plate-shaped base body 2, and these base body 2 and conductive coating layer 2a, 2b are diffusion-bonded. After forming this diffusion-bonded multilayer member into a tubular body by a drawing process, a side wall of the tubular body is formed into a bellows shape. With these processes, it is possible to obtain the bellows that has the conductive coating layer having a more uniform thickness on the base body of the bellows and has extremely good characteristics (the mechanical characteristics and the electric characteristics). |

1. A method for manufacturing bellows comprising:
arranging a flat conductive coating layer on at least one end surface side of a plate-shaped base body in layer; diffusion-bonding the base body and the conductive coating layer; forming a diffusion-bonded multilayer member into a tubular body by a drawing process; and forming a side wall of the tubular body into a bellows shape. |
